ROTARY CUTTER.l

To all whmfit mag/romeni:

Be it known'that l, CHARLES F. BALL, a Acitizen of the United States. and resident ot' `Richmond Hill, in the countv of Queens and AStateof New York, have invented a new and .useful Improvement in Rotary Cutters, of

'vertical section of the machine, -Fim Vdetail sectional View showing the adjustable' which the following is a specification.

This invention consists in improvements in 'rotary Cutters of that t vpe which are used 10V for reducing -various matters to fragments. The object of this invention is to provide certain improvements in the eonstruetioinV foi'in and arrangement of the several parts of a rotaiwv cutter whereby the operation of the machine will be faeilitated.

A -practical embodiment of my invention is represented in the-accompanying `drawin s, in 'which igure 1 is ahalf froiitview and half vertical longitudinal section,-jo f the machine, Fig. 2 is a half end view and half tranverse Slis a lower half bearing for the rotary cutter shaft, Fig. 4 is atletail view showing one of l the latches which are hinged to one cheek piece and which are arranged to engage the i other cheek piece. for lo ting the free ends pieces 11,

ofthe cheek pieces against outward movement, and Fig. 5 is a detail view of the upper half of ope ol the end plates. which also includes the upper half bearing for the` cutter shaft.

The rotary cutter shaft is denoted bv 1 and it is rovided with an)v suitable number of cutter leads -2, to which the rotaruv cutters 3 are secured. This rotary shaft is mounted between upper half bearings 4 and lower adjustable half bearings 5., the lower halt' bearings being guided in their vertical adjustment-s within recesses 6in top plates T to which the legs 8 are secured. An adjustingr ,screw 9 is provided for eac-h lower half bearing`5, which adjusting screw passes through the top plate 7 and bears against the bottoni l A casing is formed around the rotaiwv eut-tiers, which easof the said lower half bearing.

ing comprises a bottoni screen 10, cheek 12 l and end plates consisting ol' upper half sections 13 and lower haltl seetions 14. The upper half sections 13 of the end lates are formed integral with the upper alf bearings 4A and the lower half seetions 14 ofthe end plates are formed -in- Patented oct. 6. i908.

tegral with the topy plates 7. Bolts 15 serve to. secure the upper half bearings, the top plates and the legs together, leaving the screws 9 free to adjust the lower half beurings thus forming a very simple and et'- l'ective device foi takin-g lup wear in the bearings without disturbing any et the other parts of the machine. .-'i leed opening is left between the free ends ot' tht` cheek lpieces 11 and 12 and a hopper 16 is secured in position tg direct the material to be disintegrated, to the cutters. ',lhis hopper is preferably made ot' sheet metal and is provided with a top hinged door 17 and a front hinged door 1S. The front hinged door 18 is heldclosed by suitable latches 19.

The oheek ieees 11 and 12 are provided with the usua stationary adjustable cutters 20. The cheek pieces 11 and 12 of the casing are liinfred at- 21, 22, to the lower half see? half sections of the end plates are provided with eloiwated slots 23, 24, opening through the peripheryof the upper half sections of the end plates and being-concentric with the hinges 21,22, of the cheek neces. Bolts 25, 26, are located within the e onga'ted slots l 23, 24,' and have their heads bearing againstthe outer faces ofthe upper half sections of the end plates so that whenthe bolts are screwed home the cheek ieces will be clamped rigidly to the end pates. To pre.-

vent the free'eiids 'of the cheek pieces from unintentionall)Y spreadingapart when subwithout disniounting the parts, the upper' jected to great strain, 1 provide latches 27,

each of which is hinged to a holt 25 on one ol' the cheek pieces and is litted to interlock with a bolt 2G on the other cheek piece :is elearl)v shown in Fig. #1.

'hat l claim isz*- 1. ln u rtitiir \fcuttei', a bottoni screen, cheek pieces, end phites to which the cheek pieces ure hinged having elongated slots concentric with tlie hinges and opening through the sides ot' the end plates, bolts in said slot-s t'o'r clamping and releasing the cheek pieces und means for nbsolutehY locking the cheek pieces againstoutward movement..

2. 1n a rotary cutter, a bottoni screen,

thosides of the end lat for clamping and releas es, bolts in said slots mp?r the chock pieces and :means en aging certain of the bolts for absolutely loo 5 ou award movom ont.

In' testimony, that I c my invention, I have ing the cheek pieces against laim the foregoilig as signedv 'my mimo in presence of two 4Witnosses, day of April 1907.
